Definition of vacuum

By the application of medical aspiration devices, vacuum is normally given as the difference
(in absolute figures) between absolute pressure and atmospheric pressure or as negative val-
ues in kPa. In this document, the indication of -10 kPa for example always refers to a pressure
range in kPa below atmospheric ambient pressure (according to EN ISO 10079:1999).

Regulated pressure

The pressure is regularly checked and adjusted by Thopaz + . The set pressure corresponds
to the pressure of the entire Thopaz + system.

Safety pressure limit

The adjustable pressure range for Thopaz + is -0,1 to -10 kPa (-100 mbar, -75 mmHg,
-100 cmH O). If pressure values greater than -7 kPa (-70 mbar, -53 mmHg, -70 cmH O)
2 2
are set, the following warning appears in the display: too high pressure levels can cause
pain and/or serious injuries to the patient. This warning must be acknowledged with «OK»
before the pressure can be increased further.

Tube flushing

Flushing of the tubing occurs every 5 minutes or when Thopaz + detects a siphon and
prevents clogging of the patient tubing.

Safety chamber in canister

For appropriate, safe operation Thopaz + must be in an upright position. If Thopaz + tips,
the special construction of the safety chamber in the upper region of the canister protects
the hydrophilic filter from premature clogging. The pressure is maintained. Important:
immediately set Thopaz + upright again. This function is disabled if the maximum filling
capacity of the canister is exceeded.

Fluid measurement

Thopaz + detects the fluid amount in the canister by a level sensor in the device. Therefore
Thopaz + needs to stay with a tolerance of 10 ° out of axis upright and the canister must
contain a minimal fluid amount of: 25 ml in a 0.3 l canister, 50 ml in a 0.8 l canister and 150 ml
in a 2.0 l canister. If these conditions are not fulfilled the fluid values appear in grey with a
]. Additionally a Thopaz + out of axis symbol [ ] or a Thopaz +
crossed out fluid symbol [
not enough fluid symbol [ ] appears on the action bar. No additional fluid can be measured
in this status. The grey fluid values show the last measured fluid values.
The fluid measurements are displayed as accurate as follows: in a 0.3 l canister +/- 1 ml, in a
0.8 l canister +/- 5 ml and in a 2 l canister +/- 10 ml.
